The disclosure provides a clip-on desk lamp, which is fixed to the supporting structure by clamping, such as a head of a bed, a desktop and so on, so as to illuminate the area therein.
In an embodiment of the present disclosure, as shown in
In this embodiment, the first clamping part 11 and the second clamping part 12 can be disposed in a plate or a shell shape, which is not restricted here, as long as it is satisfied that the first clamping part 11 and the second clamping part 12 are hinged by the torsional spring 13. After the first clamping part 11 and the second clamping part 12 are hinged, under the effect of torsional spring 13, the first clamping fixed end 111 and the second clamping fixed end 121 apply forces to and lean against each other, to generate opposite clamping forces, so as to clamp fixed on the supporting plate. It can be understood that if the thickness of the supporting plate is less than the maximum distance between the first clamping fixed end 111 and the second clamping fixed end 121 after opening, at least one of the first clamping part 11 and the second clamping part 12 would be angled with the supporting plate after the holder 10 is clamped on the supporting plate. Taking the first clamping part 11 is angled with the supporting plate as an example, this means that only a part of the first clamping fixed end 111 positioned at an end thereof leans against the supporting plate, and the contact area is small. The smaller the thickness of the supporting plate, the smaller the contact area between the first clamping fixed end 111 and the supporting plate, and the less stable the clamping effect is.
The specific connection mode between the first adjusting plate 20 and the first clamping fixed end 111 is not restricted, as long as it is satisfied that the first adjusting plate 20 can rotate relative to the first clamping fixed end 111. The first adjusting plate 20, instead of the first clamping fixed end 111, can contact with the supporting plate, and the clamping force of the first clamping fixed end 111 can also act on the supporting plate through the first adjusting plate 20. The first adjusting plate 20 can rotate to be parallel to the clamping surface of the first clamping part 11, also can rotate to be in any acute angle with the clamping surface of the first clamping part 11. As a result, when the holder 10 clips on a supporting plate with a smaller thickness, the first adjusting plate 20 can rotate to be opposed to a supporting plate in parallel and then to lap to the supporting plate, so as to increase the lapping area with the supporting plate. The clamping force of the first clamp fixed end 111 will act on the supporting plate through the first adjusting plate 20. That is to say, the first clamping fixed end 111 would press the first adjusting plate 20 onto the supporting plate, so as not to affect the clamping force of the first clamping fixed end 111.
Thereby, the first adjusting plate 20 can not only increase the clamping area of the first clamping part of 11 with the supporting plate, but also can maintain the clamping strength of the first clamping part 11 to the supporting plate, so as to improve the clamping stability of the first clamping part of 11 relative to the supporting plate. For the supporting plates with different thicknesses, the first adjusting plate 20 can rotate to lap therewith in parallel, so as to improve the clamping effect of the holder 10 in different circumstances.
The lamp body 30 can be connected to the second clamping part 12 through a universal elbow, so that the user can adjust the illumination direction of the lamp body 30. In particular, the second clamping part 12 can include a shell and a circuit component arranged in the shell, the circuit component is electrically connected with the lamp body 30, so as to transfer electric energy for the lamp body 30, and the second clamping part 12 can play a protective role on the circuit component.
Since the lamp body 30 is installed onto the second clamping part 12, the overall weight of the second clamping part 12 is greater than that of the first clamping part 11. In the clamping state of the clip-on desk lamp, the second clamping part 12 is usually located below the supporting plate. That is to say, the center of gravity of the holder 10 is located above the supporting plate, which results in that the second clamping part 12 is easy to slide away in the direction departing from the supporting plate. And the first adjusting plate 20 installed on the first clamping part 11 makes the first adjusting plate 20 lap to the lower surface of the supporting plate, to increase the force area of the first clamping part 11 to the supporting plate, thereby limiting the slippage of the first clamping part 11, making the first clamping part 11, the second clamping part 12 and the supporting plate keep in a more stable state, to further improve the clamping effect.
In the present disclosure, the rotatable first adjusting plate 20 is provided at the first fixed end of the first clamping part 11, thereby the first adjusting plate 20, instead of the first clamping fixed end 111, is clamped on the supporting plate, so that the contact area between the first clamping part 11 and the supporting plate can be increased, to improve the clamping stability. Since the first adjusting plate 20 can rotate relative to the first clamping part 11, it can adapt to the supporting plates with different thickness or tilt angles, to improve the adaptability of the clip-on desk lamp to the clamping environment, and to improve the using effect.
In an embodiment, as shown in
The protruding lug 21 is arranged on a side of the first adjusting plate 20 facing the first clamping fixed end 111, the particular connection mode between the lug 21 and the transfer slot 112 is not restricted, as long as the rotatable fitting is satisfied. For example, the lug 21 is provided with a protruding connecting projection, and the slot wall of the transfer slot 112 is provided with a connecting hole, and the connecting projection rotatably fits with the connecting hole to implement the rotational fitting of the lug 21 and the transfer slot 112. The number of the transfer slots 112 can be multiple and the transfer slots are arranged along the length direction of the first clamping fixed end 111 at intervals, the number and the positions of the lugs 21 correspond to those of the transfer slots 112, so as to increase the connection parts of the first adjusting plate 20 and the first clamping part 11, and to improve the installation stability of the first adjusting plate 20.
In an embodiment, the lug 21 removably fits with the transfer slot 112, to facilitate the user to replace the first adjusting plate 20, so that the Whole holder 10 is not necessary to be discarded when the first adjusting plate 20 is damaged, to improve the overall service life of the holder 10.
In particular, as shown in
In an embodiment, the first adjusting plate 20 has the clamping surface 22 oriented toward the second clamping fixed end 121, and the holder 10 further includes an anti-slip mat 15 (not shown in the figures) disposed on the clamping surface 22. The anti-slip mat 15 is used to lean against the supporting plate, the friction coefficient of the anti-slip mat 15 is larger, which can increase the friction between the first adjusting plate 20 and the supporting plate, so as to prevent the first adjusting plate 20 from sliding relative to the supporting plate, and further to improve the clamping stability of the holder 10. The anti-slip mat 15 can be provided as a silicone mat to adapt to the uneven plate surface of the supporting plate through the flexible deformation, so as to improve the contact stability with the supporting plate. In addition, the silicone can further improve the anti-corrosion performance of the non-slip mat 15 to extend the service life of the non-slip mat 15.
In particular, as shown in
